In some embodiments, the rolling wheel used in the manufacture method of edge-type light guide plate can be provided by the processing roller set of edge-type light guide plate.The processing roller set of edge-type light guide plate is used for coiled strip of colding pressing to be embossed into the edge-type light guide plate with light inlet guidance part in the mode of colding pressing.
Please first see Figure 1A and Figure 1B simultaneously.Figure 1A is the front schematic view of rolling wheel one embodiment of edge-type light guide plate processing roller set.Figure 1B is the schematic side view of rolling wheel one embodiment of edge-type light guide plate processing roller set.The processing roller set of edge-type light guide plate comprises rolling wheel 100.Rolling wheel 100 comprises rolling wheel body 102, protuberance 104 and escapes to allow ditch 106.In addition, the schematic diagram that Figure 1A and Figure 1B paints also can represent the rolling wheel used in the manufacture method of edge-type light guide plate.
Protuberance 104 is formed at rolling wheel body 102, and in order to extrude coiled strip of colding pressing, wherein the diameter of protuberance 104 position is greater than the diameter of rolling wheel body 102.Escaping to allow ditch 106 be formed at rolling wheel body 102 and adjacent protrusions 104, protruding the part of distortion for holding coiled strip of colding pressing because extruding by protuberance 104.In following examples, the manufacture method of the edge-type light guide plate to this rolling wheel 100 of application is further described.
Referring to Fig. 2 and Fig. 3.Fig. 2 is the schematic side view of carrying out roll extrusion processing procedure one embodiment in the manufacture method of edge-type light guide plate, and Fig. 3 is the front schematic view of carrying out roll extrusion processing procedure one embodiment in edge-type light guide plate manufacture method.The manufacture method of edge-type light guide plate of the present invention comprises roll extrusion processing procedure, and it, by the common configuration of rolling wheel 100 with support wheel 130, provided coiled strip 110 of colding pressing forms raised structures 114.In addition, in present embodiment, the structure of rolling wheel 100 corresponds to the structure that Figure 1A and Figure 1B paints.
Cold pressing coiled strip 110 for sending between rolling wheel 100 and the common configuration of support wheel 130 according to the direction of arrow, and wherein rolling wheel 100 and support wheel 130 rotate relative to coiled strip 110 of colding pressing and impress.When protuberance 104 touch cold pressing coiled strip 110 time, the relative position of its correspondence is provided with support wheel 130, and coiled strip 110 of colding pressing will extrude because being subject to protuberance 104 and form groove 112.
Please see Figure 3.While coiled strip 110 of colding pressing forms groove 112, coiled strip 110 of colding pressing also is having near groove 112 part the stress produced because of extruding.Now, adjacent protrusions 104 and groove 112 escape allow ditch 106 become the release direction of these stress.That is, coiled strip 110 of colding pressing will be protruding to because escaping to allow ditch 106 have spatial accommodation to be escaped to allow among ditch 106, and escapes to allow the relative position of ditch 106 form raised structures 114 in correspondence.Certainly, graphicly illustration is only; In practical operation, coiled strip 110 of colding pressing is stamped the raised structures 114 of rear generation, might not fill up completely and escape to allow ditch 106, but at least can be formed in the raised structures 114 that close coiled strip 110 horizontal surface position of colding pressing is skew lines.
When roll extrusion processing procedure continues to carry out, groove 112 and the raised structures 114 of whole piece continuity will be had on the coiled strip 110 of colding pressing of roll extrusion processing procedure, as shown in Figure 2.In addition, if without escaping to allow the setting of ditch 106, the stress produced because of extruding will to be stored in coiled strip 110 of colding pressing and to become residual stress, and residual stress can make the medium of colding pressing in coiled strip 110 become uneven.
In addition, through roll extrusion processing procedure at the raised structures 114 that coiled strip 110 is formed of colding pressing, escaping on its quantity and rolling wheel 100 allows ditch 106 quantity have correlation.In some embodiments, escape to allow ditch 106 quantity be two, and it lays respectively at the both sides of protuberance 104, when coiled strip 110 is colded pressing in roll extrusion, they will at synchronous formation two (or two) raised structures 114 on coiled strip 110 of colding pressing.In other words, for coordinating volume production, a rolling wheel 100 can have n protuberance 104, and the 2n of corresponding collocation is escaped to allow ditch 106.
Similarly, escape to allow ditch 106 also have correlation with the profile of raised structures 114.In some embodiments, the escaping of rolling wheel 100 allows ditch 106 with the V-arrangement for gradually dark depression of profile view, with two inclined-planes making raised structures 114 have corresponding V-arrangement.That is, the raised structures 114 of corresponding V-arrangement, its shape on coiled strip 110 of colding pressing is by the inverted V-shaped of two incline configuration.Specifically, when carrying out roll extrusion processing procedure, escape to allow the border of ditch 106 shape can be used for limiting the profile of raised structures 114.Therefore, in Fig. 2 and Fig. 3, after roll extrusion processing procedure completes, raised structures 114 quantity of colding pressing on coiled strip 110 is two (or two), and is the inverted V-shaped by two incline configuration.
Please see Fig. 4 A and Fig. 4 B again, it is the schematic side view carrying out cutting an embodiment in edge-type light guide plate manufacture method.Present embodiment is cut the aforementioned raised structures 114 formed on coiled strip 110 of colding pressing, and the coiled strip 110 that makes to cold pressing becomes the edge-type light guide plate 120 with light inlet guidance part 122 after cutting.
After roll extrusion processing procedure completes, coiled strip 110 of colding pressing can have groove 112 and raised structures 114.Present embodiment Fig. 4 A is two with raised structures 114 quantity, and for being that example explains by the inverted V-shaped of two incline configuration.The cropped position of raised structures 114 is as shown in the dotted line in Fig. 4 A, and after having cut, groove 112 can be separated with raised structures 114, as shown in Figure 4 B.
Coiled strip 110 of colding pressing is divided into three parts after cutting, and one is the part with groove 112, and it is two for having the part of raised structures 114.And for having the part of raised structures 114, it can be used as edge-type light guide plate 120, wherein raised structures 114 is as the light inlet guidance part 122 of this edge-type light guide plate 120.Certainly, the part with groove 112 is byproducts, belongs to waste material.
In sum, by the manufacture method of above-mentioned edge-type light guide plate and the processing roller set of edge-type light guide plate, can manufacture a kind of edge-type light guide plate with light inlet guidance part, wherein light inlet guidance part is one of the forming.Specifically, light inlet guidance part is formed by crimp, and therefore, edge-type light guide plate processing roller set can define the shape of light inlet guidance part.In following examples, explain to other rollers in edge-type light guide plate processing roller set.
Please refer to Fig. 5 A.Fig. 5 A is the front schematic view that edge-type light guide plate another embodiment of rolling wheel of processing in roller set carries out roll extrusion processing procedure.In the present embodiment, rolling wheel 100 comprises rolling wheel body 102, protuberance 104 and escapes to allow ditch 106, wherein escapes to allow ditch 106 inner edge be shaped form.Escape to allow ditch 106 by curved, when coiled strip 110 of colding pressing is through protuberance 104 crimp and when forming raised structures 114, raised structures 114 will can be shaped form equally.
Please see the schematic side view of edge-type light guide plate of Fig. 5 A and Fig. 5 B, Fig. 5 B for being formed through the roll extrusion processing procedure of Fig. 5 A simultaneously.Described in the same, light inlet guidance part 122 shape that edge-type light guide plate 120 has is by escaping to allow ditch 106 define.When escaping to allow ditch 106 for time curved, the light inlet guidance part 122 formed will be similarly shaped form.In addition, what Fig. 5 A and Fig. 5 B painted escapes to allow the curve radian of ditch 106 be only illustration, and is not used to limit the present invention, persond having ordinary knowledge in the technical field of the present invention, can according to actual needs, and elasticity selects to escape to allow the curve radian pattern of ditch 106.
Please refer to Fig. 6.Fig. 6 is that the manufacture method of edge-type light guide plate uses leveling wheel to carry out the front schematic view of roll extrusion processing procedure.In some embodiments, the processing roller set of edge-type light guide plate more comprises the leveling wheel 132 with depressed part 134, and the corresponding rolling wheel 100 of leveling wheel 132 is arranged, and depressed part 134 is arranged at the position of corresponding protuberance 104.
